ELEVATOR-REG u LATO R. .9

SPECIFICATION forming part of Letters Patent No. 597,406, dated January18, 1898.

Application filed April 1'7, 1897. Serial No. 632,681, (No model.)

To all whom it may concern:

Be itknown that I, PATRICK GATELY, of the city of New York, State of NewYork, have invented'a new and useful Improvement in Elevator-Regulators,of which the following is a specification, reference being had to theaccompanying drawings.

My invention relates to means for regulating the movement of an elevatorwhich is operated by an engine embodying a reciprocatin g piston, theinvention consisting in the devices, in combination with the elevatormechanism embodying said prime mover, hereinafter set forth, andspecifically pointed out in the claims.

In the drawings, Figure l is a plan, partly in section, and Fig. 2 anelevation, partly'in section, of so much of the mechanism of an elevatorembodying my invention as is sufficient for illustration of theimprovement. Fig. 3 is a vertical transverse section taken on the line 11 in Fig. 1.

On suitable bed-pieces A A are secured two cylinders B B and guides 0for the two crossheads C- O. In the cylinders reciprocate pistons D D,being operated by steam or water, as is customary in steam or waterengines of this class, there hein g such valves and devices for openingand closing the same as are commonly used in such engines and hoistingmechanism operated thereby. The pistonrods are connected to the pistonsand cross-heads and the connecting-rods F F to the cross-heads and thecranks G G on a shaft II in the usual manner. On the shaft 11 is apinion Lwhich engages with a gear J on a shaft K, these shafts beingparallel and supported in suitable bearings, as shown. On the shaft Kare secured the drums L L, on which wind the hoisting-ropes.

To each cross-head and at each end thereof I fasten arms a, located andformed to have secured thereto a rod b, which serves as a piston-rodhaving fastened thereon a piston 0. Each piston c moves in a cylinder(1, which is secured to the bed-piece and has a stuffingbox e at eachend for the piston-rod 1). Opening into each end of each cylinder cl isa pipe f, in which is a valve g. Each of these valves is operated bymeans of a stein h, a rack i, and pinion j. These pinions are allsecured on ashaft it, having suitable bearings, as

shown, and rotated by means of a pulley Z, fastened on the shaft, and arope in, which extends around the pulley Z and a pulley n. The pulley itmay be so located that the rope may pass through the elevator-car to beoperated by a person in the car.

The cylinders d and the pipes f being filled with oil or other liquidand each piston c being reciprocated in the corresponding cylinder d bymeans of and in accordance with the movement of the piston of the steamor water engine, the liquid will be forced back and forth in eachcylinder (1. The speed of motion of this liquid'and therefore the speedof the engine will be determined by the size of the passage at eachvalve g. Therefore by moving this valve by means of the rope m, as abovedescribed, so as to make the passage thereat such as may be required,the movement of the elevator may be regulated from the car as desired,it being of course understood that the valves g are to be operated withsuch reference to the ordinary valves of the engine as not to cause anundue strain on the working parts.

I claim as my invention 1. In hoisting mechanism embodying a steam orWater engine, and in combination with the cylinder, piston andcross-head of said engine, a stationary cylinder at each side of saidcross-head, and a piston therefor secured to said cross-head,substantially as specified.

2. In combination with the cross-head of an engine of a hoistingmechanism,.arms secured to said cross-head, a piston-rod secured to saidarms, a piston on said rod, a cylinder in which said piston moves, apipe connecting the ends of said cylinder to form a continuous passagetherewith, a valve in said pipe, a stem provided with a rack andconnected to said valve, a pinion to engage with said rack, a shaft forsaid pinion provided with a pulley, and a rope extended about saidpulley and guided so as to be manipulated at a suitable position as intheelevator-car, substantially as set forth.

In combination with a hoisting-engine, arms secured to the cross-head ofthe engine at each end thereof, a fixed cylinder at each side of theengine, a piston in each of said cylinders provided with a piston-rodwhich is fastened to said arms to move with the crosshead, a pipeconnecting the ends of each cylinder to form a continuous passagetherewith, a valve in each of said pipes provided with a stem and rack,a pinion to engage with each of said racks, the several pinions being onone shaft which has thereon a pulley, and a rope extending around saidpulley and guided to a suitable position for manipulation as in theelevator-car, substantially as set forth.
